About Kasumigaseki
Kasumigaseki (霞ヶ関) is a neighbourhood in Tokyo, and the seat of the Japanese government. The name means "gate of fog", and what's fog but a cloud on the ground?
Kasumi doesn't demand attention. It simply exists.
That's how we think about infrastructure. The best infrastructure is the kind you don't notice—until you need it. It should work silently, reliably, without friction. It should disappear into the background.
What We Do
Kasumigaseki builds tools for the modern internet. We focus on the fundamental problems that developers and operators face: connectivity, security, and reliability.
Wirebus solves a problem as old as the internet itself: getting a public IP address to your machine. No matter where your servers live—behind CGNAT, in a container, on your home network—Wirebus gives you a real IPv4 address that works.
We're based in Singapore, building for the global internet.
How We Work
Simplicity
Complexity is the enemy. We build tools that do one thing well, with the minimum necessary configuration.
Reliability
Infrastructure must work. We design for failure, test for edge cases, and build robust systems that are a joy to work on.
Elegance
Good engineering is beautiful. Good solutions solve problems without creating new ones.
